在下面的代码片段中，用于连接到 SQL Server 的网络协议(protocol)是什么？ TCP/IP 或命名管道或其他？
using System;
using System.Data.SqlClient;
class Program
{
static void Main()
{
//
// First access the connection string.
// ... This may be autogenerated in Visual Studio.
//
string connectionString = "Server=SERVER\\INSTANCE;Database=myDataBase;User Id=myUsername;
Password=myPassword;"
//
// In a using statement, acquire the SqlConnection as a resource.
//
using (SqlConnection con = new SqlConnection(connectionString))
{
//
// Open the SqlConnection.
//
con.Open();
//
// The following code uses an SqlCommand based on the SqlConnection.
//
using (SqlCommand command = new SqlCommand("SELECT TOP 2 * FROM Dogs1", con))
using (SqlDataReader reader = command.ExecuteReader())
{
while (reader.Read())
{
Console.WriteLine("{0} {1} {2}",
reader.GetInt32(0), reader.GetString(1), reader.GetString(2));
}
}
}
}
}
最佳答案
根据 SQL Server Native Client Configuration :
Protocols are tried in the order listed, attempting to connect using the top protocol first, and then the second listed protocol, etc.
但是，我们还读到:
These settings are not used by Microsoft .NET SqlClient. The protocol order for .NET SqlClient is first TCP, and then named pipes, which cannot be changed.
这就是他们将尝试的顺序 - 首先是 TCP，然后是命名管道 - 因此不会使用“一个”协议(protocol) - 这取决于成功。 p>
